TELESCOPIC DRINKING-CUP.

Speccation of Letters Patent No. 28,597, dated June 5, 1860.

T o all whom it may concern:

Be it known that I, PETER H. NILES, of Boston, in the county of Suffolk and State of Massachusetts, have invented an Improved or Telescopic Drinking-Cup; and I do hereby declare the same to be fully described and represented in the following specification and the accompanying drawings, of which Figure l, is a side view of the said cup as shut together or collapsed and covered. Fig. 2, exhibits it in a distended state and uncovered. .Figa 3, is a section of it when collapsed and covered. Fig. 4, is a section of it when distended and uncovered.

On November 2nd, 1858, Letters Patent, No. 21955, were granted to Louis Grosholz for an improved drinking cup, composed of a short cup and one or more annular frustra, both cup and frustra being made conical or with inclined sides. The objection to such a cup, is, that the parts of which it is composed are not only liable to fall apart and separate when the cup is inverted, but the rings are liable to collapse or fall down `around the lower part while the cup may be distended, all of which is obviated by my improved construction of cup.

In carrying out my invention I make the cup or bottom part and each annulus or ring cylindrical in form and one to slide either on or into the other. j Y

In the drawings A, exhibit-s the smaller cup or bottom part, while B, and C, are its tubular parts or rings. Each ring as well as the smaller cup I form with two flanges a, b, projecting respectively from the top and bottom of its external surface as shown in the drawings. I also form each ring with a groove, c, extending around it and l at the lower part of its inner surface.

Furl thermore, I make the cover D, so as to shut and fit into the upper part of the smaller cup A, and with a flange, d, to extend and lap over all the upper edges of the part A, and its ring or rings B, C, as shown in Fig. 2.

Each upper flange, a, of the cup A, and ring B, as well as the groove, c, to operate with such flange should be so made that the flanch may be sprung into the groove when the parts bearing such flanch and groove are drawn axially from one another-the same serving to hold the parts in place when the drinking cup is distended.

The lower flanches of the cup and rings Z), Z), prevent them from falling apart when the whole are inverted so as to cause the mouth of the cup to stand downward. So while the cover is in place it will preventthe distention of the cup.

I do not claim a combination consisting of a cup and one or more annular sections constructed and applied to it as shown in the aforementioned patent.

My improved cup can be made to good advantage, either from metal or from the composition known as hard vulcanized 'rubber, the latter material having considerable elasticity, which contributes to form close joints between the flanches and the recesses.

I claim- Making the cup or bottom part A, and one or more of its annular sections B, C, with bottom flanches Z), b, and applying the cover so as to fit the bottom part A, and projectover the same and the upper edges of its annular section or sections as described.
